MapInitializeEvent cannot be triggered asynchronously from inside synchronized code.

Describe the bug
I have created a plugin which creates an image and places it on ItemFrame, the code works fine for all other forks or paperspigot or spigot itself but gives an error in WindSpigot.

Bug on latest
Yes

Expected behavior
It should put the map on itemframe

Can you try re-downloading the latest release and testing again?
